Abstract

The invention discloses an organic conjugated polymer containing a porphyrin skeleton structure as well as a preparation method and application of the organic conjugated polymer. An organic conjugated metal organic polymer with a main chain containing a porphyrin skeleton structure is designed and synthesized, a porphyrin structure with a high pi conjugated system, high structural stability and easy processing is connected with a thiophene group, and the conjugation performance of the material structure is further enhanced. The organic conjugated polymer containing the porphyrin skeleton structure is compounded with a single-walled carbon nanotube (SWCNT), and the loading rate of the SWCNT in a composite film formed by the organic conjugated polymer containing the porphyrin skeleton structure and the SWCNT is adjusted, so that a film material with relatively high thermoelectric performance can be obtained, and the highest PF value is 400.11 mu W m <-1 > K <-2 >. 本发明公开一类含有卟啉骨架结构的有机共轭聚合物及其制备方法与应用。本发明设计并合成了一类主链含有卟啉骨架结构的有机共轭金属有机聚合物，将具有高度π共轭体系、高结构稳定性、易加工的卟啉类结构与噻吩类基团相连接，进一步增强材料结构的共轭性能。将其与单壁碳纳米管(SWCNT)进行复合，通过调整含有卟啉骨架结构的有机共轭聚合物与SWCNT形成的复合薄膜中SWCNT的负载率，可以得到具有较高热电性能的薄膜材料，最高PF值为400.11μW m‑1K‑2。
